What it is

Nisin preparation is a natural antimicrobial substance produced by the bacterium Lactococcus lactis. It is produced through fermentation and then purified. Nisin works by disrupting the cell membranes of certain bacteria, inhibiting their growth.

Why it's used

Manufacturers add nisin preparation as a preservative to prevent spoilage by bacteria. It is commonly found in dairy products, processed meats, and baked goods, helping to extend shelf life and maintain food safety.

Health notes

Nisin preparation is generally recognized as safe (GRAS) by the FDA for use as an antimicrobial agent in food. International bodies like JECFA and EFSA have evaluated nisin and found it to be safe for consumption. At typical intake levels found in food, it is not associated with adverse health effects.

Allergen info

Nisin is produced by bacteria and is not derived from major allergens. It does not contain gluten.
